Keratin: The Hair Shield
We've all seen signs of weak hair, whether it’s frizz, dryness, split ends, or breakage. These issues often arise when the hair lacks its outermost protective layer, which shields it from various damaging factors. Let's take a moment to get familiar with this important hair protector, Keratin, and explore tips to enhance its strength for healthier hair.


What is Keratin?

Keratin is a type of protein that the body can naturally produce, and it’s the main component of hair, nails, and skin. In fact, about 90% of our hair is made up of keratin.

The outer layer of the hair is made up of hard keratin cells stacked like fish scales, forming the cuticle. Beneath the cuticle lies the cortex and medulla. The cuticle acts like a shield, protecting the hair from UV rays, heat, chemicals, and pollutants. It also prevents moisture loss from the inner layers.

When the keratin scales are well-aligned, hair appears smooth, shiny, and healthy. This alignment strengthens the hair’s structure, making it more resilient to stress and preventing split ends and breakage.

Keratin and Hair Damage

Did you know that during certain times, like when hair is wet, the cuticle can open, making hair more vulnerable to damage and moisture loss? This is especially true when washing your hair or swimming. Be cautious with chemical treatments like hair coloring, straightening, or perming, as they can strip the hair of its keratin.

How to Boost Keratin for Healthier Hair

You can help restore keratin in your hair by consuming protein-rich foods, including biotin (Vitamin B7), which supports keratin structure. Great choices for keratin-boosting foods include eggs, nuts, liver, salmon, kale, carrots, sweet potatoes, and sunflower seeds. These not only nourish your hair but also benefit your skin and nails, which also rely on keratin.


Deep Hair Treatment for Fuller, Healthier Hair

For those looking to take their hair care a step further, focusing not just on keratin but on overall hair health, we recommend the PHB Treatment Program. This treatment involves targeted scalp injections to address hair thinning and shedding. It enhances hair strength, making it appear thicker and healthier from the inside out, with no side effects. Results can be observed after just a few sessions, especially for those with early signs of hair thinning.

If you have any concerns about your hair, whether it’s thinning or other issues, feel free to consult with our experienced doctors at Namnin Clinic. We’ll help you design the most effective treatment plan tailored to your needs.
